  • Hi Joel,

    I can't thank you enough for your answers.
    You're exactly the guy I was hoping would answer.
    I was at your Networkers RF talk in 2006 so I knew you'd have the answers.
    They are exactly what I was looking for.
    I am totally thrilled.
    (Yeh I know ... sounds a bit over the top but I was starting to dispare of getting satisfying answers).

    BTW these TX powers are what Cisco Auto-RF converged on after several days of (as far as I can can tell) RF stability. This is a new site and a large campus and AirmAgnet Laptop Analyzer and Spectrum Analyzer say it's RF quiet. There are no microwave ovens or cordless phones operating etc. because there's noone else here to operate them. The neighbours are a long way away.
    The Auto-Rf threshold set by CLI command,
    config advanced 802.11b tx-power-control-thresh <value>
    had been changed from default of -65 to -71.

    Even at -71 I'm starting to think Auto-Rf converges on too high a Tx power. At the default (-65) the Tx power Auto-RF converges on is even higher (as expected) = worse.

    I'm coming to the same conclusion of excess Tx power by Auto-RF for 2.4G & 5G based on the output of the
    show ap auto-rf 802.11b <AP name?
    and
    show ap auto-rf 802.11a <AP name?
    commands
    Nearest APs section.

    Regards, MH
